Rings from the 1920s often feature intricate platinum settings, geometric motifs, and old cut diamonds, bridging the gap between Edwardian delicacy and bold Art Deco design.

Jewellers used yellow gold for the shank to provide structural warmth and strength, while platinum was utilised for the settings because its strength allowed for minimal metal usage and maximum light reflection on the diamonds.

Authentic pieces typically exhibit hand-cut diamonds such as old European or old mine cuts, hand-engraved details, makers marks, and precious metal assay hallmarks appropriate to the period.

Due to potential differences in metal hardness and historical profiles, pairing an antique ring with a matching vintage band or incorporating a spacer band helps prevent friction wear.

Clean antique rings gently using warm soapy water and a soft brush, avoiding harsh ultrasonic cleaners which can dislodge stones in aged settings.
